Figure 3 is a section of the cross-piece B, which shows a groove, O.

General Description.

The same letters refer to corresponding parts in the several figures.

A is 4the frame.

B B are cross-pieces.

Imake my frame of ash timber, three by'five.

inches. The frame is thr-e'feet wide and five feet long, and about twofeet eight inches high, or more, if desired. l v

I cnt a groove in the cross-piece or pieces, to iiisert.the gum-elasticand gibs, and for the piece H to slide in, over which are screwed thecaps G, which I make of brass or iron. The gibs are also made of brassor iron. The gibs are made by bending a dat piece of iron or brass, ofthe proper width and thickness, at right angles at each end.

The mot-ion of my saw may be increased to any desired speed, by placinga pulley ou the end of the shaft D, in place of the crank N, or acog-wheel may be-used, and gearing applied to increase the speed as muchas is desired.

I do not claim an upright saw, as I am aware they have been used.

I am aware of the sawing-machine of H. L'. Beach, and do not claimanything as my invention contained in his machine'as claimed by him.
